Adam Radwan scored a hat-trick of tries as Newcastle made it six wins from six in Challenge Cup Pool One after a 33-19 win over Enisei-STM.

Federico Giliberti went over for an early try that Aleksandr Budychenko converted to give the hosts an early 7-0 lead, but Newcastle rallied with tries from Mark Wilson, Radwan (two) and Toby Flood, who converted three times to give the Falcons a 26-7 half-time lead.

Anton Sychev crossed to get the home side back into the game before Radwan completed his hat-trick and Mikheil Gachechiladze added a late consolation for the Georgian side.

Dragons edged into second place in the pool on points difference after beating Union Bordeaux Begles 33-17.

London Irish boosted their own faint hopes of qualifying as a best-placed runner-up with a 24-17 victory at Krasny Yar.

Niyi Adeolokun scored a first-half hat-trick as Pool Five leaders Connacht ended the group campaign with a 50-14 win over Oyonnax.

Bundee Aki, Tiernan O’Halloran, Matt Healy and Thomas Farrell also went over for Connacht, who were awarded a penalty try, too.

Worcester Warriors were denied a place in the knockout stages after losing their final pool match to Brive, who won 33-7 in a delayed kick-off after the game was switched from its scheduled venue.

Warriors required at least two points from their final group fixture to guarantee their place in the quarter-finals, but Brive went over for five tries to clinch a bonus point win needed to leapfrog them into second place.

Brive’s home ground, the Stade Amedee-Domenech, was water-logged so kick-off was delayed four-and-a-half hours while the venue was switched to nearby Stade Alexandra Cueuille.
